带有元素列表的映射字典

本文关键字：映射字典列表元素 | 更新日期: 2023-09-27 18:10:31

是否可以使用Fluent NHibernate来映射具有以下签名的属性?

IDictionary<NavigationType, IList<NavigationActionEntity>> NavigationActions;

NavigationType为enum, NavigationActionEntity为映射实体。
我试着这样做:

HasManyToMany(x => x.NavigationActions).AsEntityMap()
                                       .Table("CarrierNavigationActions");

但是它给了我一个例外:

An association from the table CarrierNavigationActions refers to an unmapped
class: System.Collections.Generic.IList`1[[Dal.Entities.NavigationActionEntity]]

带有元素列表的映射字典

这里有一个跳圈

class ActionsHolder
{
    protected IList<TypeToEntity> innerList { get; set; }
    public IDictionary<NavigationType, IList<NavigationActionEntity>> NavigationActions
    { get { return new NavigationTypeMap(innerList); } }
}
class TypeToEntity
{
    public virtual NavigationType Type { get; set; }
    public virtual NavigationActionEntity NavigationActionEntity { get; set; }
}
class MyClassMap : ClassMap<ActionsHolder>
{
    public MyClassMap()
    {
        HasMany(Reveal.Member<ActionsHolder, IEnumerable<TypeToEntity>>("innerList"))
            .Table("NavTypeToNavActionEntity")
            .Component(c =>
            {
                c.Map(x => x.Type);
                c.References(x => x.NavigationActionEntity).Not.LazyLoad();
            })
            ;
    }
}
class NavigationTypeMap : IDictionary<NavigationType, IList<NavigationActionEntity>>
{
    private IList<TypeToEntity> innerList;
    public NavigationTypeMap(IList<TypeToEntity> innerList)
    {
        // TODO: Complete member initialization
        this.innerList = innerList;
    }
    // TODO: implementation of IDictionary<>
}
